BUT: if you really believe,that you can manage all that stuff WITHOUT ANY KNOWLEDGE, you are simply wrong. Either the forum cannot help you with only a few postings.

You cannot setup Apache, MySQL, PHP, (Linux?), Joomla and and and without the slightest idea of what you are doing there. You should take your time, read tutorials, try to understand how these tools are working and how they are working together - we cannot (and will not) explain all these stuff in a few postings. This is quite impossible.
